A combined GNSS and FM receiver receives FM signals comprising satellite navigation data from an AGNSS server. Associated navigation information such as a position fix is determined based on the received satellite navigation data. The received satellite navigation data are GNSS assistance data or LTO data. The AGNSS server generates the satellite navigation data by acquiring GNSS data from a satellite reference network. The acquired GNSS data comprise, for example, GPS data, GLONASS data and/or GALILEO data. The generated satellite navigation data are broadcasted as FM signals through RDS and/or RBDS to the combined GNSS and FM receiver. The combined GNSS and FM receiver receives updated satellite navigation data in subsequent FM signals, periodically or aperiodically, and updates associated navigation information, accordingly. The combined GNSS and FM receiver decodes the received FM radio signals for the updated satellite navigation data generated at the AGNSS server before being transmitted.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for processing signals, the method comprising: receiving, from an FM radio base station, broadcast FM radio signals comprising satellite navigation data, wherein said satellite navigation data is acquired by said FM radio base station from an assisted global navigation satellite systems (AGNSS) server; and determining navigation information based on said satellite navigation data received via said broadcast FM radio signals, wherein said satellite navigation data received via said broadcast FM radio signals comprise assisted GNSS data and long term orbit (LTO) data.
2. A method for processing signals, the method comprising: receiving, from an FM radio base station, broadcast FM radio signals comprising satellite navigation data, wherein said satellite navigation data is acquired by said FM radio base station from an assisted global navigation satellite systems (AGNSS) server; and determining navigation information based on said satellite navigation data received via said broadcast FM radio signals, wherein said satellite navigation data comprise GPS data, GLONASS data and/or GALILEO data.
3. The method according to claim 1 , further comprising receiving said satellite navigation data via said broadcast FM radio signals through one of a radio data system (RDS) or a radio broadcast data system (RBDS).
4. The method according to claim 1 , further comprising receiving updated satellite navigation data via subsequently received broadcast FM radio signals.
5. The method according to claim 4 , further comprising updating said navigation information based on said received updated satellite navigation data.
6. The method according to claim 4 , wherein said updating of said navigation information occurs periodically or aperiodically.
7. A method for processing signals, the method comprising: receiving, from an FM radio base station, broadcast FM radio signals comprising satellite navigation data, wherein said satellite navigation data is acquired by said FM radio base station from an assisted global navigation satellite systems (AGNSS) server; and determining navigation information based on said satellite navigation data received via said broadcast FM radio signals, comprising determining subsequent navigation information based on said received broadcast FM radio signals comprising said satellite navigation data.
8. The method according to claim 1 , further comprising decoding said received broadcast FM radio signals comprising satellite navigation data.
9. The method according to claim 1 , wherein said satellite navigation data is generated by said AGNSS server prior to being transmitted as said broadcast FM radio signals.
10. The method according to claim 2 , further comprising receiving said satellite navigation data via said broadcast FM radio signals through one of a radio data system (RDS) or a radio broadcast data system (RBDS).
11. The method according to claim 2 , further comprising receiving updated satellite navigation data via subsequently received broadcast FM radio signals.
12. The method according to claim 11 , further comprising updating said navigation information based on said received updated satellite navigation data.
13. The method according to claim 11 , wherein said updating of said navigation information occurs periodically or aperiodically.
14. The method according to claim 2 , further comprising decoding said received broadcast FM radio signals comprising satellite navigation data.
15. The method according to claim 2 , wherein said satellite navigation data is generated by said AGNSS server prior to being transmitted as said broadcast FM radio signals.
16. The method according to claim 7 , further comprising receiving said satellite navigation data via said broadcast FM radio signals through one of a radio data system (RDS) or a radio broadcast data system (RBDS).
17. The method according to claim 7 , further comprising receiving updated satellite navigation data via subsequently received broadcast FM radio signals.
18. The method according to claim 17 , further comprising updating said navigation information based on said received updated satellite navigation data.
19. The method according to claim 7 , further comprising decoding said received broadcast FM radio signals comprising satellite navigation data.
20. The method according to claim 7 , wherein said satellite navigation data is generated by said AGNSS server prior to being transmitted as said broadcast FM radio signals.
